Detailed ways

In order to make the objects, technical solutions and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

It is found that in a slot, when the first uplink signal and the second uplink signal need to be transmitted simultaneously, it is necessary to consider the beam coordination problem of the two. If the multiplexing mode and the rate matching information of the two are directly determined without considering the beam coordination problem, the signal cannot reach the receiving end due to the inconsistent understanding of the beam between the base station and the terminal. For example, the transmit beams of the Physical Uplink Shared Channel (PUSCH) and the Physical Uplink Control Channel (PUCCH) are inconsistent. The base station and the terminal agree that when the PUCCH and the PUSCH are transmitted in the same slot, the PUCCH needs to be used. The control information included in the PUSCH is transmitted in the PUSCH, and the transmission information included in the PUSCH channel is uniformly transmitted in the PUSCH channel and the control information included in the PUCCH is used. However, since the terminal does not receive the scheduling information of the PUSCH, the terminal continues to use the PUCCH on the PUCCH. The original transmit beam transmits the signal, and the base station has adjusted its transmit beam to the transmit beam of the PUSCH, which causes the terminal to transmit to the base station through the signal transmitted on the PUCCH. Further, in one slot, when the first uplink signal and the second uplink signal need to be simultaneously transmitted, it is necessary to consider the beam coordination problem of both. If the multiplexing mode and the rate matching information of the two are directly determined without considering the beam coordination problem, the signal cannot reach the receiving end due to the inconsistent understanding of the beam between the base station and the terminal.

If the first transmit beam and the second transmit beam belong to the same transmit beam group, and the terminal may not simultaneously generate the first transmit beam and the second transmit beam, the third transmit beam is obtained according to the first transmit beam. If the first transmit beam and the second transmit beam belong to different transmit beam groups and the terminal can simultaneously generate the first transmit beam and the second transmit beam, the third transmit beam is obtained according to the first transmit beam; if the first transmit beam and The second transmit beam belongs to the same transmit beam group, but the terminal cannot simultaneously generate the first transmit beam and the second transmit beam, and the third transmit beam is obtained according to the second transmit beam.

For example, the first signal is an uplink control signal, and the second signal is an uplink data signal, and the uplink control signal and the uplink data signal need to be sent in one time unit (such as a slot, and of course, other time units are not excluded). As shown in FIG. 3, the downlink data channel PUSCH on the slot n+k1 is triggered by the DCI (Downlink Control Information downlink control information) on the slot, and the terminal also needs to send the PUCCH on the slot n+k1, but the PUSCH is sent. The beam (ie the second spatial filtering parameter of the second signal) is different from the transmit beam of the PUCCH (ie the first spatial filtering parameter of the first signal), wherein the transmit beam of the PUSCH is signaled by the DCI scheduling the PUSCH, and/or the higher layer signaling It is notified that the transmit beam of the PUCCH is notified by scheduling the DCI of the PUCCH, or the DCI of the PDSCH is scheduled, wherein the PUCCH includes the ACK/NACK feedback information of the PDSCH, or the transmit beam of the PUCCH is notified by the high layer signaling, for example, the channel state information is included in the PUCCH. In particular, when the periodic channel state reports information, in summary, the time-frequency resource occupied by the data signal and the control signal and the transmission beam of the data signal and the control signal are obtained through the signaling information as shown in FIG. 3 (FIG. 3 is only an example). , other time-frequency resources are not excluded. Because of beam-based transmission, further consideration should be given to the multiplexing side of PUSCH and PUCCH. .

For example, the PUCCH and the PUSCH cannot be frequency division multiplexed, and cannot be code division multiplexed. Reuse, or discard one of them.

Alternatively, when the transmit beam of the data and the controlled transmit beam terminal can be simultaneously generated, the data and control can be transmitted on the same time domain symbol, such as PUCCH and PUSCH frequency division multiplexing and/or code division multiplexing. When the data transmission beam and the controlled transmission beam terminal cannot be generated at the same time, the data and control cannot be transmitted on the same time domain symbol. For example, PUCCH and PUSCH cannot be frequency division multiplexed, nor can code division multiplexing, only time division multiplexing. , or discard one of them.

If the indication signaling indicates that the UCI and the PUSCH can be transmitted on separate channels, the terminal needs to further determine the multiplexing mode between the UCI and the data according to the relationship.

For example, the predetermined multiplexing manner of the first signal and the second signal is frequency division multiplexing/code division multiplexing/space division multiplexing, or the resources occupied by the first signal and the second signal are in the time domain. Steps 1 to 3 in this embodiment are required to be performed. Otherwise, steps 1 to 3 in this embodiment are not performed.

If the signal is a received signal, the opposite end is the transmitting end. If the opposite ends of the two signals belong to the same group, step 1 to step 3 in this embodiment are performed.

Example 3

In this embodiment, the terminal performs the following steps:

Step 1: determining a relationship between a first spatial filtering parameter of the first signal and a second spatial filtering parameter of the second signal;

Step 2: Determine, according to the relationship, a resource occupied by the first signal and/or a resource that is determined to be occupied by the second signal;

Step 3: transmitting the first signal and/or the second signal on the determined resource;

The resource includes at least one of the following resources: a time domain resource, a frequency domain resource, a code domain resource, and an airspace resource.

For example, when scheduling across slots, the resources of the PUSCH scheduled on the slotn are as shown in FIG. 5, but there is PUCCH scheduling on slotn+1, slotn+2 (for example, the PUCCH may be a PUCCH with periodic CSI feedback, or the PUCCH is in Slotn+1, aperiodic CSI feedback triggered on slotn+2, and of course other PUCCH resources are not excluded. In this case, the transmission beams of the PUSCH and the PUCCH may be inconsistent, and the resources occupied by the PUSCH need to be further determined. On the slotn+1, the transmit beams of the PUSCH and the PUCCH do not belong to the same group, and the PUCCH has a higher priority than the PUSCH. The PUSCH needs to perform rate matching on the time domain symbol where the PUCCH is located, or the PUSCH does not transmit, as shown in FIG. . On slotn+2, the transmit beams of PUCCH and PUSCH belong to the same transmit beam group (one of the transmit beam groups indicates that the terminal can be generated simultaneously, and/or the same transmit beam group indicates that the base station can receive simultaneously), then slotn+2 The PUSCH and the PUCCH can be simultaneously transmitted. The PUSCH does not need to perform rate matching on the time domain symbol where the PUCCH is located, and the two can be transmitted in their own independent channels as shown in FIG. 6. UCI can also be transmitted in PUSCH on slotn+2.

Steps 1 to 3 in this embodiment may also be changed to the following steps:

Step 1: determining a relationship between a first reference signal associated with the first signal and a second reference signal associated with the second signal;

Step 2: Determine, according to the relationship, a resource occupied by the first signal and/or a resource that is determined to be occupied by the second signal;

Step 3: transmitting the first signal and/or the second signal on the determined resource; for example, obtaining a first spatial filtering parameter of the first signal according to the first reference signal, according to the second reference signal A second spatial filtering parameter of the second signal is obtained.

The spatial filtering parameters of the signal are mentioned in the above embodiments. This embodiment specifically describes the manner of acquiring the spatial filtering parameters of the signal.

For example, if the signal is a PUSCH, the spatial filtering parameter of the PUSCH may be obtained by establishing an association between a PUSCH Demodulation Reference Signal (DMRS) and an uplink measurement reference signal, such as establishing a DMRS and an SRI. The association between the SRS resource and the SRS resource is an uplink reference signal, so that the transmission spatial filtering parameter of the PUSCH is obtained according to the transmission spatial filtering parameter corresponding to the SRS indicated by the SRI. In some embodiments, the association between the DMRS and the other uplink reference signals of the physical uplink shared channel (PUSCH) may be established, where the other uplink reference signals include: a Preamble sequence for transmitting random access, and a physical uplink. The DMRS of the control channel (PUCCH, Physical uplink control channel), the DMRS of the other PUSCH, and the resource request signal, so that the transmission spatial filtering parameters of the PUSCH can be obtained according to the transmission spatial filtering parameters of the reference signal associated therewith.

Alternatively, an association between the DMRS of the PUSCH and a downlink reference signal may be established, and the transmission spatial filtering parameter of the PUSCH is obtained according to the receiving filter parameter of the downlink signal received by the terminal. Or the transmission spatial filtering parameter of the PUSCH is obtained according to a transmission spatial filter of the base station of the downlink reference signal associated with it (that is, a reception filtering parameter used by the base station to receive the uplink signal). The downlink reference signal includes at least one of the following: a measurement reference signal, a demodulation reference signal, a synchronization signal, and a phase tracking reference signal.

The association between the signal and the reference signal may also be a QCL quasi-co-location association, that is, the channel characteristic parameter of the signal may be derived according to a channel characteristic parameter of the reference signal, where the The channel characteristic parameters include at least one of: delay spread, Doppler spread, Doppler shift, average delay, average gain, average vertical transmission angle, average horizontal transmission angle, average vertical angle of arrival, average horizontal angle of arrival, center Vertical transmission angle, center horizontal transmission angle, center vertical arrival angle, and center horizontal arrival angle.

The spatial filtering parameter group is mentioned in the above embodiment, and the embodiment specifically describes the acquisition mode of the spatial filtering filtering parameter group.

The spatial filtering parameter group may be notified by the base station. For example, different SRS resources represent different transmitting beams, and the base station notifies that some SRS resources belong to one group, for example, the receiving beams of the base stations corresponding to the SRS resources are the same, or the base station can receive one at the same time. An SRS resource group cannot receive resources in different SRS resource groups at the same time. Therefore, the base station can receive the signal as long as the terminal transmits the signal by using the transmit beam in the SRS resource group. Alternatively, different SRS resource base stations in one SRS resource group may not be simultaneously received, and different SRS resource base stations in different SRS resource groups may receive simultaneously.

In some embodiments, for example, the base station notifies that the SRS1 and the SRS2 belong to the same transmit beam, and when there is an association between the DMRS and the SRS1 of the PUSCH and the DMRS of the PUCCH and the SRS2, the transmission spatial filtering parameters of the PUSCH and the PUSCH can be obtained. The transmission spatial filtering parameters of the PUCCH belong to the same spatial filtering parameter group, as shown in FIG.

The method for obtaining the spatial filtering parameter group may also be sent by the terminal. For example, the SRS resource terminal of the SRS resource group may be generated at the same time, and the SRS resource terminal of the different SRS resource group may not be generated at the same time. Or the SRS resources in one SRS resource group cannot be generated at the same time, and the SRS resource terminals in different SRS resource groups can be generated at the same time.

Or the method for obtaining the spatial filtering parameter group is that the base station notifies the adding terminal to send a common determination, for example, the SRS resource group notified by the base station belongs to a resource group sent by the terminal. Or different SRS resources in the SRS resource group notified by the base station are from different SRS resource groups sent by the terminal.

The method of obtaining the spatial filtering parameter set described above may also be used in some embodiments for the acquisition of SRS reference signal groups, and/or SRS reference signal resource groups.

In this embodiment, the first signal is specifically described according to the channel on which the second signal is located.

In some embodiments, for example, the first signal is uplink control information (UCI), and the second signal is data information. When there is no data scheduling, the UCI is transmitted on the PUCCH.

When there is data scheduling, it is necessary to confirm which channel the first signal is located as follows:

The first signal is transmitted on a channel on which the first signal is located, such as UCI transmitted on the PUCCH;

The first signal is transmitted in a channel where the second signal is located, for example, the UCI is transmitted on the PUSCH and is not transmitted on the PUCCH;

The first signal is transmitted both in the channel in which the first signal is located and also in the channel in which the second signal is located. For example, UCI is transmitted on both the PUSCH and the PUCCH.

In this embodiment, the terminal sends a delay to the base station to switch the spatial filtering parameters, where different spatial filtering parameters correspond to different transmitting beams, and/or different panels.

For example, the terminal has four spatial filtering parameters {parameter 1, parameter 2, parameter 3, parameter 4}, wherein the switching delays of different parameter pairs are different, for example, the switching delay between {parameter 1, parameter 2} is delay 1 For example, the switching delay between {parameter 1, parameter 3} is delay 2, the terminal can group the parameter pairs, the switching delays in the same group are the same; or group the parameters to switch the different reference signals in different groups. Delay to inform the base station.

Or the terminal informs the base station of the minimum of the handover delays of all parameter pairs. For example, {parameter 1, parameter 2} corresponds to switching delay 12, {parameter 1, parameter 3} corresponds to switching delay 13, {parameter 1, parameter 4} corresponds to switching delay 14, {parameter 2, parameter 3} corresponds to switching Delay 23, {parameter 2, parameter 4} corresponds to handover delay 24, {parameter 3, parameter 4} corresponds to handover delay 34, and the terminal reports to the base station {switch delay 12, handover delay 13, handover delay 14, handover The delay 23, the switching delay 24, and the maximum value in the switching delay 34}. Or the terminal notifies the base station of these handover delays.

When different spatial filtering parameters are characterized by different reference signals or different reference signal resources, the switching delay of the spatial filtering parameters may also be referred to as a switching delay of the reference signal.

In this embodiment, the resources that the first signal can occupy change according to the resources occupied by the second signal;

In some embodiments, for example, the first signal is a data signal, the second signal is a control signal, the end time domain symbol position of the data signal is represented by two bits of DCI, and the resources occupied by the second signal are different, the two bits The end time domain symbol position of the representation can be different.

As shown in FIG. 8a, the resource occupied by the PUCCH is the 14th OFDM symbol in one slot, and the meaning of the two DCI representations for notifying the PUSCH end time domain symbol position is as shown in Table 1:

DCI value End position of PUSCH 0 11 1 12

As shown in FIG. 8b, the resource occupied by the PUCCH is the {13, 14} OFDM symbol in a slot, and the meanings of the two DCI representations that notify the PUSCH end time domain symbol position are as shown in Table 1:

DCI value End position of PUSCH 0 10 1 11

As shown in FIG. 8c, the PUCCH does not occupy resources in this slot, and the meaning of the two DCI representations that notify the PUSCH end time domain symbol position is as shown in Table 1:

DCI value End position of PUSCH 0 12 1 13

Further, the time domain symbol range that the end position of the first signal can occupy can be determined according to the relationship information of the first reference signal and the second reference signal and the resource occupied by the second signal. Wherein the first reference signal is associated with the first signal, or the first reference signal is associated with a demodulation reference signal of the first signal, wherein the second reference signal is associated with the second signal, or the second reference signal and the second signal are demodulated Reference signal correlation.

In this embodiment, the relationship between the first signal and the second signal, the first signal and the second signal may be signals that satisfy at least one of the following conditions:

The first signal and the second signal have the same transmission direction (for example, the first signal and the second signal are both uplink signals, or the first signal and the second signal are both downlink signals);

Transmitting the first signal and the second signal in a time unit, for example, the transmission time unit is a slot, or is a subframe;

The first signal or the second signal includes at least one of: a data signal, a control signal, a reference signal, a random access signal, and a resource request signal;

Control signaling that triggers the first signal transmission before triggering the second signal control signaling;

The information of the first signal is obtained by high layer signaling;

The information of the second signal is obtained by physical layer dynamic control signaling;

The first signal is triggered by high layer signaling;

The second signal is triggered by physical layer dynamic control signaling;

The first signal has a higher priority than the second signal.

The target user of the first signal is different from the target user of the second signal. For example, when the signal is an uplink signal, the first signal may be a transmission signal of the first user, and the second signal may be a transmission signal of the second user; or For example, when the signal is a downlink signal, the first signal may be the received signal of the first user, and the second signal may be the received signal of the second user.

In this embodiment, the resources occupied by the first signal are changed according to the resources occupied by the second signal, for example, the first signal is a PUSCH channel signal, and the second signal is a PUCCH signal. When it is determined that the information included in the PUCCH (such as the periodic CSI information) can be transmitted in the PUSCH channel, that is, the UCI and the data are all transmitted in the PUSCH, the resources occupied by the PUSCH are the PUSCH resources and the PUCCH occupied in the PUSCH scheduling information. Resources These two resources (such as the resources occupied by the PUCCH of the high-level signaling), as shown in Figure 9, the two resources are combined into one resource for transmitting UCI and data information on the PUSCH, as shown in the right half of Figure 9. Show. The resource situation occupied by the two resources in FIG. 9 is only an example, and other embodiments are not excluded in this embodiment. For example, if it is determined that the UCI cannot be transmitted in the PUSCH, the resources occupied by the PUSCH are as shown in the left half of FIG.

In this embodiment, the demodulation reference signal of the first signal changes according to resources occupied by the second signal, for example, the first signal is PUCCH, the second signal is PUSCH, and it is determined that two channels are required to be transmitted by time. If the frequency domain resource occupied by the PUCCH is a subset of the frequency domain resources occupied by the PUSCH, the demodulation reference signal in the PUCCH is not transmitted. Preferably, the resources occupied by the demodulation reference signal of the PUCCH can be used to transmit control information in the PUCCH.

And if there is a demodulation reference signal in the demodulation reference signal of the PUSCH and the start time domain symbol distance of the PUCCH is less than a predetermined value, the demodulation reference signal in the PUCCH is not transmitted. Preferably, the resources occupied by the demodulation reference signal of the PUCCH can be used to transmit control information in the PUCCH.

In this embodiment, the multiplexing manner of the first signal and the second signal is determined according to a switching delay of the first spatial filtering parameter of the first signal and the spatial filtering parameter of the second signal.

For example, when the first signal is the PUSCH and the second signal is the PUCCH, when the transmission time interval between the two is confirmed by the scheduling information to be greater than or equal to the handover time delay, the PUCCH and the PUSCH may be time-divisionally transmitted on the respective channels;

For example, when the first signal is the PUSCH and the second signal is the PUCCH, when the transmission time interval between the two is smaller than the handover time delay by using the scheduling information, one of the PUCCH and the PUSCH needs to be discarded, or the UCI is included in the PUCCH. Put it in the PUSCH for transmission.

The handover delay may also be the capability information reported by the terminal, that is, the different spatial filtering parameter pairs are not distinguished, the switching delays of all spatial parameter pairs are the same, or the switching delay is different for different spatial filtering parameters. The minimum value is taken in the switching delay. As shown in Example 7.

In this embodiment, the transmission manner of the first signal is determined according to the relationship between the first signal opposite end indication information and the second signal opposite end indication information.

When the signal is sent, the opposite end is the receiving end indication information. For example, when the signal is an uplink signal from the terminal side, the opposite end base station end or the communication node end. When the signal receives the signal, the opposite end is the transmitting end indication information. For example, when the signal is a downlink signal from the terminal side, the base end or the communication node end corresponding to the opposite downlink signal.

As shown in FIG. 10, when the opposite end indication information of the first signal is 1 (corresponding to TRP1), when the opposite end indication information of the second signal is 2 (corresponding to TRP2), such as the opposite end indication information 1 and the opposite end indication information 2 The first signal and the second signal are not transmitted in one channel, and are respectively transmitted in separate channels, or cannot be combined as one information block before channel coding for joint coding, and each channel is independently coded. As such, both the first signal and the second signal are configured with independent transport channels and/or code channels. If the peer indication information 1 and the peer indication information 2 belong to one group, the first signal and the second signal are combined and transmitted in one channel, or one information block before the channel coding is jointly coded. The peer indication information group information may be sent by the base station to the terminal, or the terminal may send to the base station, for example, the terminal informs the base station that the two uplink signals cannot be combined, because these are sent from different transmission panels, for example, respectively from FIG. The transmission panel 1 or the transmission panel 2 is shown. In some embodiments, a peer indicates that there is an ideal backhaul between the communication nodes in the packet, or the geographic location is very close, or the transmission delay is less than a certain threshold. For example, the high-level signaling notifies the peer indicating information group, the dynamic signaling signal indicates the opposite end indication information, or determines whether their peer indication information belongs to a group according to whether the first signal and the second signal correspond to the same DCI group. The DCI group is distinguished by at least one of the following resources of the DCI: a common control resource set (Coreset), a candidate set, a search space, an aggregation level, and a QCL reference signal associated with the demodulation reference signal of the DCI. For example, if the DCI for scheduling the first signal and the DCI for scheduling the second signal are the same, the opposite indication information of the first signal and the second signal belong to the same peer indication information group.

The public control resource set may carry information such as a part of the lightsaber system information carried by the physical broadcast channel or information carried by the physical downlink virtual channel, and is exemplified herein, but is not limited thereto.

In some embodiments, according to the opposite end indication information of the first signal, when the opposite end indication information of the second signal indicates that the information is the same opposite end indication information, the transmission manner of the first signal and the second signal is determined, for example, If the opposite end indication information of a signal is different from the opposite end indication information of the first signal, the first signal and the second signal may not be combined in one channel for transmission, and each is transmitted in a separate channel, or may not be formed as a channel coding. One information block is jointly coded and independently channel coded. If the opposite end indication information of the first signal and the opposite end indication information of the first signal are the same, the first signal and the second signal are combined and transmitted in one channel, or are composed. A block of information before channel coding is jointly encoded. In the present application, the spatial filtering parameters may also be referred to as beam parameters, channel characteristic parameters, precoding weight parameters, or other equivalent names, which do not have a substantial impact on the inventiveness of the present application. The spatial filtering parameters include transmitting spatial filtering parameters, and/or receiving spatial filtering parameters.
